The Simpsons

As they enter their tenth season, The Simpsons are still a
record-breaking show. No other annimated series has lasted as long as The Simpsons.

The show started off of the The Tracey Ullman
Show on April 19, 1987. It didn't appear as a series until April 1989 when it first
appeared on its Sunday night at 8:00 Eastern (7:00 Centeral) time slot. The first three seasons
were animated by Klasky-Csupo, an animator for The
Tracey Ullman Show. That is why they appear to be different compared to episodes
since.
